In periodic cellular structures,novel pattern transformations are triggered by a reversible elastic instability under the axial compression.Based on the deformation-triggered new pattern,periodic cellular structures can achieve special mechanical properties.In this paper,the designed architecture materials which include elastomer matrixes containing empty holes or filled holes with hydrogel material are modeled and simulated to investigate the mechanical property of the periodic materials.By analyzing the relationship between nominal stress and nominal strain of periodic material,and the corresponding deformed patterns,the influence of geometry and shapes of the holes on the mechanical property of architecture material is studied in more details.We hope this study can provide future perspectives for the deformation-triggered periodic structures.
